Default How much power does a welder use

I have a Kemppi Master 1400 Stick welder that I'd like to be able to use
aboard my boat
I have a 2400w inverter fitted that I think is a square wave, might be
modified square wave.
or... I do have access to a 3.5kv generator. would either of these run it.
The Kemppi has a maximum output of 140amp, but at what is the voltage, how
many watts do I need to strike the ark etc

thanks
